- A group of environmentalists is studying the effects of recent commercial zoning to wildlife acreage on the biodiversity of a rural county. The group noted a steady decline in the population of animals, while bacteria and other protists remained constant. Which statement best discusses the reasons for the steady decline of animals as opposed to the protists? A. Bacterial growth is usually not affected by environmental changes because of asexual reproduction. B. The animals could not adapt to the new environment. C.
